Strontia Springs Reservoir lies in a steep, forested canyon along the South Platte River in Douglas County, serving as a primary water supply for the Denver metropolitan area while also offering some of the most scenic and rewarding fishing in the Front Range. The reservoir is not a drive-up destination — reaching it requires hiking through the Bear Creek Trail corridor, a lush, canyon-bottom path that visitors describe as jungle-like in its dense vegetation and towering rock walls.
The effort to get here pays off. Anglers who make the trek report catching quality rainbow trout, with fish in the 16-inch range not uncommon. The reservoir's role as a municipal water supply means it receives consistent management attention, and the cold, deep water supports a healthy trout fishery. The surrounding canyon amplifies the sense of remoteness, making it feel far more wild than its actual proximity to the Denver suburbs would suggest.
Access to Strontia Springs Reservoir is controlled, and visitors should check current regulations before planning a trip. Because the reservoir is part of Denver Water's infrastructure, certain areas along the shoreline may be restricted, and boating is not permitted. The hike in along Bear Creek is moderate in difficulty but can be slippery after rain, and the trail passes through areas with significant elevation change.
The canyon setting provides dramatic scenery in every season. Spring brings rushing water and wildflowers along the trail. Summer offers shaded hiking under a canopy of cottonwoods and willows. Fall transforms the canyon into a corridor of gold and amber. Winter access is possible but conditions can be icy and challenging.
Strontia Springs Reservoir rewards visitors who are willing to work for the experience. With a 4.4-star rating, it draws consistent praise for its stunning natural beauty and quality fishing, balanced by honest notes about the effort required to reach the water. For hikers and anglers looking for a genuine backcountry feel within an hour of Denver, this reservoir delivers.
